It looks so complicated. You must have used a lot of selfmade bitmaps.
No, actually I've only used a couple of templates to create the images. As it is a repetitive process it is very simple. On the other hand, I have a hobby to create new icons. I like it.
This tool is for users with midicontrollers, right?
Yes. With a Midi controller keyboard you can compose with live recording, but not edit. This tool allows editing with the mouse and with the midi Input. In fact, you could compose a song without using an alphanumeric USB keyboard. Also, I added the ChordPad with the same capacity. You can add chords with the mouse or with any Midi pad. The tool is designed to be compact. You can select the columns you want to display.
It may seem a bit complex. But the compressed tool does not occupy more than 100KB.
